[Means for solving the problem]

According to the means of the present invention, the end of the winding core 2 is placed in the holding recess 1'provided at the tip of the holding body 10 which is the assembly portion in the piece winding machine for winding the piece 9 around the flat plate-shaped winding core 2. The pair of core holders 1 are arranged to face each other so as to be fitted and held, and the first opening portion 7 is formed by opening the entire front wall portion of the holding recess 1 ′ facing the narrow front surface of the winding core 2. Forming a second open portion 8 by opening a part of the upper surface wall portion of the holding recess 1 ′ facing the wide upper surface of the winding core 2 that is continuous with the first open portion 7. , It is in.

Further, the rear piece 6 forming the rear wall portion of the holding recess 1 ′ facing the narrow rear surface of the winding core 2 is slidable in the front-back direction with respect to the holding body 10, and the width of the winding core 2 is wide. A lower piece 4 forming the lower surface wall portion of the holding recess 1 ′ facing the lower surface or the upper surface or an upper piece 3 forming the upper surface wall portion.
Is effectively slidable in the vertical direction with respect to the same holding body 10.

[Action]

To assemble the winding core 2 to the holder 1, the latter half of the end of the winding core 2 is placed on the lower piece 4 from the second opening 8 and then the upper surface of the lower piece 4 is used as the guide surface 11. The winding core 2 may be slid between the upper piece 3 and the lower piece 4 until it abuts on the rear piece 6.

That is, the insertion of the winding core 2 into the first opening portion 7 is achieved with the winding core 2 placed on the lower surface 4 from the second opening portion 8. Therefore, the holding recess 1 of the winding core 2 The fitting and assembling work in the ′ is extremely easily accomplished.

The size of the second open portion 8 is not particularly limited as long as the end portion of the winding core 2 can be easily placed on the guide surface 11.

When assembling the winding core 2 to the holder 1,
There is no need to push back the holder 1 and the worker does not move the core 2
You only have to deal with it.

Further, the core 2 assembled to the holder 1 is in a state where the portion facing the first opening 7 and the second opening 8 is exposed from the inside of the holding recess 1 ′, so the core 2 The cloth 9 wound around the core is directly wound around the exposed core 2 portion. Therefore, after winding, a gap is unlikely to be formed between the core 2 and the cloth 9, so that the cloth 9 is loosened. Without core 2
Will be wound up.
